Q)

A transistor is operated in common-emitter configuration at $V_c=2V$ such that a change in the base current from 100 µA to 200 µA produces a change in the collector current from 5 mA to 10 mA. The current gain is :


( A ) 50
( B ) 75
( C ) 150
( D ) 100

1 Answer

Comment
A)
Current gain, beta = delta Ic/ delta Ib =(16.5-9)*10^-3/(200-100)*10^-6 Beta=75
